, To all whom 'it may concern:

Be it known that I, WILLIAM J. CUNNING- HAM, a citizen of the United States, residing in the city and county `of Philadelphia, State of Pennsylvania, have invented a new and useful Receptacle-Filling Valve, .of which the following is a specificat1on.

My invention relates to a new and useful receptacle filling valve which is more especially adapted foruse in fill-ing receptacles and consists of means for permitting the escape of air from the receptacle whenthe fluid is caused to flow thereinto.

It further consists in providing means for conducting the air which escapes from the receptacle to a point where it exerts pressure upon the upper surface of the fluid which is to enter the vessel. It further consists of novel details of construction all as -Will be hereinafter fully set forth. 1

Figure 1 re resents a vertical sectional view of the va ve. tical sectional view showingv the parts in a different position. y

Similar numerals of reference indicate correslpondin'g parts in the figures.

eferring4 to the drawings: I have vfound in plractice, that in order to fill a receptacle W1t fluid, it is necessary not only to control the fluid but also to provide some means for l -the easy escape of the air from the receptacle in order that thefluid will flow thereinto and my invention is designed more especially for this purpose. In addition,y I take the air from the receptacle and conduct the same to a point above the surface of the liquid which is to flow into the vessel, in order that it will act as an additional ressure upon the fluid.

In the drawings I ave shown a construction for carrying out my invention but it will be apparent .that other instrumentalities may be employed and certain changes made, which will accomplish the same results and I do not, therefore, desire to be limited to the eXact construction as shown and described, but wish to make such changes aslmay be necessary. l

1 designates a tank or reservoir only a portion of ywhich is shown and which maybe of any suitable size or dimension and whichfis provided with an opening 2, in which .is seated a sleeve 3, provided with ports 4 communicating with the interior of the tank and having a flange .5 thereon which abuts against the bottom of the tank 1. Secured Fig. 2 represents a ver-y to said sleeve in any desired manner and in the present instance by the threads 6is a receptacle 7.

8 designates a movable sleevev which is provided 1n the present instance with the .ports 9 adapted to normally register with the ports 4 in the sleeve 3, said sleeve 8 having the head 10 thereon, against which, is adapted to bear, a spring 11 which also in the present instance, bears against the flange 5 so that the movable sleeve 8 and sleeve 3 are normally held, in the position seen in Fig. 1, -with the ports registering. l

12 designates a pipe which is suitably secured to a suitable point of the receptacle 7 y and is provided with the downwardly turned end 13, which projects asuitable distance into the said receptacle in order that said pipe will discharge into the upper portion of said receptacle. -Screwed orv otherwise secured to the pipe 12 is a cap or head 14 to which is attached a sleeve 15, which is provided with port's-16, it being noted that the head 10 ofthe sleeve 8 is normally seated in such a manner with respect to the ports 16, that the same are closed so that said head 10 serves as a valve for said ports. The tube 15 projects upwardly a slight distance into the sleeve'8 and the upper portion of said tube 15 is open to the interior of said sleeve 8. A cap 17 is screwed or otherwise `secured to the head 10 which latter may also be provided with the resilient-,washer 18.

The o eration of the de'vice will be readily seen. he reservoir 1 is filled with milk or j other fluid and the port 4 is in re ister with the' ort 9 in the sleeve so that t e milk or flui fills the tube 15, the sleeve 8 and interior of the receptacle 7, the ports 16 of the tube 15 being closed. When the bottle or other receptacle is placed beneath the valve and a pressure is exerted upwardly by the bottle or by a downward movement, if imparted to the reservoir 1, the cap 17, head1() and sleeve 8 are moved with respect to the sleeve 3 and receptacle 7. That is to say, there is a relative movement between these parts so that the ports 4 are closed and the' ool thereof empty and as said head 14 and tube 12 are within the bottle, air from the latter passes up through the tube 12 and downwardly t irough the end 13 thereof into the lu er portion of the receptacle 7, actlng as additional pressure for forcing the fluid from the receptacle 7, it being noted thatthe capacity of the receptacle 7 and sleeve 8 are e ual to the capacity of the bottle to be filled. As soon as the ports 16 are closed which occurs by the action of the spring 11 when the pressure is removed the orts 4 again register with the ports 9 and t e milk or fluid again flows into the receptacle7 and 1'5 sleeve 8, ready for the next operation.

The construction above described is more particularly adapted for use in machines where a plurality of valves are employed,to fill a plurality of bottles and I preferably use 20 the valve in a construction of machine where the tank is moved downwardly against the bottle, so that the head 10 contacting with bottle, com resses the spring 11, opening the ports 16. t will be further apparent that I may, if desired, shorten the sleeve 8 so that the upper end thereof is normally below the ort 4, thus dispensing with the necessity of aving the ports 9. In lieu of screwing the head 14 to the tube 12 I may employ some other means for securing the tube 12 in posi-v tion with respect to the receptacle 7.

It will be noted that the cap 17 is rovided with the inclined or curved inner wa 19 and that the head 14 is provided with the inclined 3,5 or curved outer wall 20, whereby the two walls act as guides to roperly center the bottle with respect to tllfe valves and direct the mouth of said bottle properly against the Washer or gasket 18, it being necessary that the bottle is in proper osition before the orts 16 are o ened, so t at the fluid cannot gow until the ottles are ready 'to receive the lsame and thus none of the fluid will be lost. It will be noted also that the relation of the head 10 With the ports 16 is such that there ,is a slight movement-permitted before the ports are opened, which is an additional safeguard agamst accidental flow of the liquid before the bottle is properly centered.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is z* 1. In a device of the character described, a tank adapted to hold liquid, a measuring rece tacle having an inlet normally open, a disc arge opening from said receptacle, means normally closing said opening and adapted to be actuated to close said inlet when said discharge opening is opened,
